A short-leaved type with dark green, erect leaves. Grows more slowly than the long-leaved variety Grote Noordhollandse" and is somewhat more sensitive to stem rot in the winter. Sow in rows in the garden. Also suitable for cultivation in a heated greenhouse and indoors. After emergence do not thin out. Grow in well worked soil that has been fertilised with compost. Keep moist. Good resistance to frost. A very vitamin-rich winter vegetable."
